I had second thoughts about that part after realizing that callers
cannot tell the difference between "ps_display is disabled" and
"the activity part of the display is currently empty".  In the latter
case I think we'd rather have WaitOnLock still append " waiting";
and it's not like PS_USE_NONE is so common as to be worth optimizing
for.  (Else we'd have identified this problem sooner.)

Minimal fix pushed, so please adjust that animal's config.
